Wrasse: Ballan, Cuckoo and Other UK Species

By Alex Clayton · Updated 23 October 2026

Every ballan wrasse starts life as a female.

The ballan wrasse (Labrus bergylta) is the largest UK wrasse, a stocky, thick-lipped fish of kelp beds, rock gullies and harbour walls. It is the classic rock-mark species, and the fish most anglers mean when they talk about wrasse fishing.

This guide covers the five UK wrasse you are most likely to hook: ballan, cuckoo, corkwing, goldsinny and rock cook. It shows how to tell them apart, which baits and methods work on rough ground, and what the size rules say, because they differ by IFCA and by nation.

Ballan and Cuckoo Wrasse at a Glance

These are the key numbers for the two wrasse anglers target most.

	Ballan wrasse	Cuckoo wrasse
Scientific name	Labrus bergylta	Labrus mixtus
Maximum length	Up to around 60 cm, though most are much smaller	Males up to 35 cm, females up to 30 cm
Rod-caught size	British records just over 9 lb (4.1 kg)	Rarely over 12 in or 2 lb (0.9 kg); shore fish usually under 1 lb
Depth and ground	Shallow rock, kelp and harbour walls	Hard ground from 2 to 200 m, mainly 20 to 80 m
Colour	Mottled green, brown or reddish	Females pink or orange-red; males orange with a blue-striped head

Published ballan maximums range from 50 to 69 cm, so treat any single figure with caution. Ballan lifespan and diet are covered below, and the records are in the FAQ.

How to Tell UK Wrasse Species Apart

The same rock mark can give you three or four different wrasse in one session, and most guides only help you name one. Check the body shape first, then the colour, then look for a tail spot.

Species	Key marks	Size	Where you find it
Ballan	Stocky body, thick lips, mottled green, brown or reddish	By far the largest UK wrasse	Shallow rock, kelp, harbour walls
Cuckoo	Slimmer body; females pink or orange-red, mature males orange with a blue-striped head	Small to medium	Deeper hard ground
Corkwing	Dark spot at the base of the tail	Small	Rock marks
Goldsinny	Dark spot near the top of the tail root	Rarely over 6 in (15 cm)	Rock marks
Rock cook	A small wrasse named alongside corkwing and goldsinny in IFCA and Scottish rules	Small	Rock marks

With cuckoo, judge colour and sex together. A pink fish and an orange fish with a blue-striped head, caught from the same mark, can both be cuckoo wrasse.

The name also decides which rule applies, because Cornwall IFCA and Scotland treat each species differently (see the size limits section below). For other fish from the same trip, see our sea fish identification guide.

Ballan Wrasse Life Cycle, Diet and Behaviour

The fish you catch on a summer evening could be older than some of the anglers fishing for it. Ballan wrasse can live for up to 30 years.

They also change sex. All ballan begin as females, and the most dominant fish later become males. That makes the biggest fish on a mark the likeliest breeding males, which is a strong reason to put large fish back.

Their diet explains your bait choice. Ballan pull molluscs and barnacles off the rock and crush the shells with teeth in their throat, and they also eat crabs, sea urchins and small fish. That is why crab and shellfish baits work so well.

In winter they tuck into rocky crevices, so the fishing slows right down once the water cools.

The cuckoo wrasse spends more of its life in deeper water.

Cuckoo Wrasse: The Deeper-Water Wrasse

The blue-and-orange fish and the plain pink one beside it can be the same species. Cuckoo wrasse females are pink or orange-red, while mature males turn orange with blue stripes across the head.

Cuckoo wrasse live around most coasts of Britain and Ireland, on rocky and hard ground from 2 to 200 m deep, mostly between 20 and 80 m. They sit slightly deeper than ballan.

These are small fish, so scale down your hooks and baits. Boats fishing over rough ground, and rock marks where deep water runs close in, give you the best chance of one. Cornwall IFCA does not allow cuckoo to be kept alive under its live-wrasse rules.

Where the ballan is a heavy, shallow-water fish, the cuckoo is smaller, lives deeper and is far more colourful.

Where and When to Catch Wrasse in the UK

Wrasse switch off in a big swell. Rough, choppy seas send them into hiding, and cold water pushes them deeper.

Look for structure. Heavier rock marks with kelp hold the most wrasse and the biggest ballan. Pier and harbour walls work too, because wrasse patrol the stonework picking off shellfish, so float-fish ragworm tight to the wall rather than casting into open water. Our guide to rock fishing in the UK covers how to pick and read a mark.

Because ballan hide in crevices over winter, wrasse fishing is mainly a warmer-months game, and calmer days fish best. To work out when your mark fishes on the tide, see our guide to tides for sea fishing.

If your local mark is clean sand, you are in the wrong place. Move to the rocks or the harbour wall.

Wrasse Fishing Baits, Rigs and Lures

Wrasse ground eats tackle, so build rigs strong and expect to lose some. Some rock anglers use old spark plugs as throwaway weights, which tells you how they feel about tackle loss.

Best baits for wrasse

Ragworm: often better than lugworm, and the go-to for steady bites. See ragworm as a sea bait.
Peeler crab and hardback crab: the best baits for bigger ballan. See how to use peeler crab.
Mackerel strip: works on its own, and a little mackerel scent can help a crab bait.
Shellfish: natural food for a fish that crushes shells for a living.

Ballan suck worms off the hook, so secure them with bait elastic.

Three methods compared

Method	Best for	Watch out for
Float rig with an adjustable float	Keeping bait clear of weed and snags; fishing tight to rock or harbour walls; changing depth quickly	Struggles in heavy swell
Bottom rig (running or flapper style)	Big crab baits for large ballan, with hooks around 2/0	Snags and tackle loss on foul ground
Soft plastics on LRF or HRF gear	Jelly worms rigged weedless or Texas-style; short, stumpy plugs also work	Needs fish-holding structure; less proven for the very biggest fish

On the float, go shallower if nothing bites. See our guide to fishing floats, and the sea fishing rigs guide for rough-ground bottom rigs. Use strong, abrasion-resistant line for both.

Lure fishing for ballan wrasse brings hard takes on light gear, and our LRF fishing guide covers the approach.

For goldsinny and corkwing, use tiny baits on hooks in sizes 6 to 10 (see the fishing hook sizes explainer).

Wrasse Size Limits and the Cleaner-Fish Fishery

The “9 in minimum size” quoted on several angling sites has no legal source we could find, and the official sources we checked set no UK-wide recreational minimum. The limits that exist are commercial.

Wrasse are caught alive in pots and traps for salmon farms, where they work as cleaner fish against sea lice. Ballan made up 71.6% of Scottish wrasse landings from 2017 to 2024, according to the Scottish Government assessment published on 13 June 2025, and little is known about current stock levels.

Rules as checked on 23 October 2026:

Area	Who it covers	Key points
Cornwall IFCA	Live-wrasse permit holders	Ballan minimum 16 cm, closed 1 January to 31 March. Goldsinny, rock cook and corkwing 12 cm, closed 1 May to 30 June. Cuckoo may not be kept alive. Unclear whether anglers are bound.
Devon and Severn IFCA	Category One commercial potting permit holders	Slot sizes for ballan, corkwing, cuckoo and goldsinny (check the IFCA for values). Rock cook cannot be removed from the district.
Scotland	Commercial trap fishery	Ballan 14 to 24 cm for 2025 (minimum raised from 12 cm). Cuckoo 12 to 24 cm. Goldsinny, rock cook and corkwing 12 to 17 cm. Season 1 May to 30 November. Maximum 250 wrasse per vessel per 24 hours. Anglers not addressed.
Wales and Northern Ireland	No wrasse rules found in our research	Check with the Welsh Government or DAERA.

Rules change, so check your local IFCA or national authority before keeping any wrasse. See also UK sea fish minimum sizes and fish size and take limits.

Handling, Releasing Wrasse and Staying Safe on Rock Marks

A landing net and a wet towel solve most wrasse handling problems. The dorsal fin carries sharp spines, and a wet towel gives you a safe grip while you unhook the fish.

Wrasse are sensitive to pressure change, and fish brought up from deep water can die at the surface. Unhook quickly and get the fish back in fast. Our catch and release guide covers the basics.

Check tide times and the swell forecast before you go, wear a lifejacket, and follow RNLI and HM Coastguard advice. Read our fishing safety guide before your first session on the rocks.

The same rough ground often holds pollack and bass, and on some marks cod in winter. Browse the UK sea fish species hub for more.

Frequently asked questions

Can you eat ballan wrasse?

Yes, but ballan wrasse are not a popular eating fish and most anglers return them, not least because one can live for up to 30 years. The Cornwall Good Seafood Guide notes some demand from Japanese restaurants.

What is the British record ballan wrasse?

Published transcriptions of the British Record Fish Committee list give the ballan shore record as 9 lb 1 oz (4.11 kg), Portland, Dorset, 1998, and the boat record as 9 lb 7 oz 12 dr (4.30 kg), Jersey, 1999. For cuckoo wrasse they give 1 lb 12 oz 9 dr from the shore (Herm, 1999) and 2 lb 7 oz 12 dr by boat (Dungeness, 1998). Records change, so check the current list on the Angling Trust's British Record Fish Committee page.

Is there a minimum size for wrasse in the UK?

Not that we could find in official sources. The rules that exist are commercial live-wrasse limits, such as the Cornwall IFCA 16 cm ballan minimum and the Scottish 14 to 24 cm slot. Check your local IFCA or national authority before keeping any fish.

What is the best bait for ballan wrasse?

Peeler or hardback crab is the best bait for bigger ballan wrasse, while ragworm brings steady bites. Fish either under a float or on a strong bottom rig close to the rock.
